DRINKING FLASK

摘要

A drinking vessel comprises a body part (10) to receive a drinks liquid, a lid (30) to seal the top of the body part, a liquid outlet passage (50, 52) extending down to a lower region of the interior space of the body part, and an air intake passage (54) also extending down to the lower region of the interior space of the body part. As the user draws liquid out of the vessel through the liquid outlet passage (50, 52), replacement air enters through the air intake passage (54) and then bubbles upwardly through the liquid within the vessel.
